The HTML5 version of the game lags and loses players
Any browser game lives by a simple law: the longer it takes to load and the more often it stutters, the faster players leave for competitors. The visitor doesn't know and doesn't want to know how the game works inside.
They see only one thing: their battle is interrupted, the animation breaks apart, and the picture "freezes." After the second such case, they close the tab, and a third one never happens — because the player doesn't come back.
For business, this is a silent loss of revenue that's hard to notice right away. You invest in attracting visitors, pay for advertising and marketing, and the game "filters them out" before they complete the desired action.
Every lost player is not only unearned revenue but also damaged reputation: on social media and forums, people write not about your mechanics or story, but about "lags and freezes." Negative reviews scare off new players more powerfully than bad advertising.
The cause is usually not the game itself, but how it's adapted for the browser. An HTML5 version built incorrectly wastes resources: it loads unnecessary data, doesn't use the capabilities of modern browsers, and "lags" even on powerful computers.
Fixing this with simple "cosmetic" tweaks isn't possible — a full re-architecture for the browser environment is needed.
We solve the problem through professional HTML5 porting to Unity. We configure the build so it runs stably on different devices, distributes the load properly, and loads quickly even on average internet connections.
As a result, the game launches smoothly, visitors stay on the site longer, complete more levels, and are more willing to return. Which means — conversion to payment grows without additional advertising spend.
What HTML5 porting gives: access without installation and audience growth
Access without installation is the main advantage of HTML5 porting. Your clients don't want to wait for a download: while a person is thinking about whether to install the file, they often leave for competitors.
The game opens via a link in any modern browser — on a computer, tablet, or smartphone. One click, and the user is already inside, and contact with the brand begins with instant "launch."
Audience growth is a direct result of this approach.
The game is easy to send via messenger, publish on social media, or embed on a website: nobody needs to "figure out how to install it." This is especially important for mobile audiences — people play right in the browser, without app stores.
Reach grows through viral mechanics: you can share with one touch, and friends of subscribers get into the game the same way.
We create browser versions on Unity — a professional tool that delivers a stable picture and smoothness across different devices. The player doesn't see the technology but feels the quality: fast loading, responsive controls, clear interface.
For you, this means sessions run without failures, and the brand doesn't look like a "lagging toy." We adapt the project for different browsers so the result remains predictable for every visitor.
A browser game easily connects with analytics and forms: you can see where users linger, whether they reach a request or a purchase. You can add promo codes and entry mechanics to turn game interest into real sales.
This way, gamification becomes a measurable growth tool and helps increase conversion, not just entertain.
Game porting formats for your task
We port games to HTML5 turnkey — from a simple browser version to full adaptation with social mechanics. So you don't overpay for extras, we've divided the work into three formats: basic, standard, and premium.
| Format | Best for | What you get |
|---|---|---|
| Basic | Landing page, promo campaign | Fast launch in the browser on any device. Embedding on a website in a couple of days. |
| Standard | Regular campaigns | Adaptation to your design, leaderboard, setup for website and social media. |
| Premium | Large launches | CRM integration, player analytics, unique mechanics, and post-release support. |
How to choose the right format? A simple checklist:
- Basic — if you need a quick start, a minimal budget, and the game as a business card.
- Standard — if it's important that the game works identically on all devices and collects record statistics.
- Premium — if the game becomes part of marketing: you need analytics, integrations, and maintenance.
We'll give a recommendation after a free brief — it takes half an hour. In all three formats, we work turnkey: we test the browser version on computers, tablets, and smartphones, and the code stays with you for repeated launches.
Game porting stages: from brief to launch
We port the game to HTML5 so you don't have to guess what's happening at each step. The process is transparent: you see timelines, understand the budget, and control the result — from the first brief to launch.
It all starts with a short brief: you tell us which game we're porting, who plays it, and which outcome matters most — reach, engagement, or brand involvement. Then we put together a work plan and estimate timelines — without surprises or "sudden" stages.
-
Brief and audit of the original game. We record the goals, target audience, and constraints. We review the source code and graphics — what gets ported and what is better simplified for fast loading in the browser.
-
Work plan and timeline estimate. We break the project into stages, show timelines for each, and agree on the budget. You get a clear roadmap with expected results.
-
Prototype approval. We launch a draft version of the game in the browser. You see how the game looks and feels and make adjustments before the main development begins.
-
Development and layout for all screens. We adapt controls, interface, and animations — so the game works equally well on a computer, tablet, and smartphone. At this stage, we check loading speed and stability.
-
Testing on real devices. We check player scenarios, the correctness of saves, and behavior on weak internet connections. You receive a testing report — without hidden "technical nuances."
-
Launch and post-support. We place the game on your platform or advertising channel and stay in touch after launch: we fix issues and help with updates.
At each stage, you receive an intermediate result and can influence the course of the work. No "black boxes" — only clear decisions, fixed timelines, and a result that works for your business.
What's included in delivery: launch kit
When we hand over the project, you get not just a link to the game, but a complete delivery package for launch and independent development. This removes dependence on the contractor and gives your team transparent control over the product.
- Project source files: full code, scenes, all assets, and settings. They stay with you — you can rebuild the game, hand it to another team, or modify it without restrictions.
- Documentation: a structured description of the logic and key decisions. A new specialist will get up to speed in days, not weeks.
- Update guide: step-by-step instructions for replacing content, adding levels, and publishing versions. You can release updates without our involvement.
- Test and release builds: optimized files that already work in the browser on any modern device. For your hosting and domain — just upload and play.
- Team training: a hands-on session with your developers or content managers, where we cover typical tasks and answer questions.
- Technical support and warranty: consultations during the first weeks after launch to keep the project running stably and your team feeling confident.
These aren't checkbox files, but a working system where you fully control your product. Every item in the package is aimed at making the game your asset, not someone else's headache.
Case study: how we brought a game to life for a cinema chain
For the large cinema chain Kinopark, we turned an ordinary popcorn simulator into a live tool for attracting audiences.
Previously, the game could only run from a special device or after a long installation — so only a handful of people played it, and the marketing potential remained untapped.
We moved the game to HTML5 technology, and now it opens instantly right in the browser — from a smartphone, tablet, or lobby screen.
The guest doesn't need to download anything: they see the call-to-action, press "Play," and within seconds they're already collecting popcorn. For the chain, this means the entertainment is available to anyone with a phone — and that's the majority of visitors.
Metrics the client saw
A month after launch, the time guests spend in the game grew by 40%.
People started returning to it repeatedly, and the number of subscriptions to movie premieres increased by almost a third — the content turned out to be so engaging that players left their contacts on their own so as not to lose their progress.
What the business got
The tool works toward the main goal — increasing attendance and the base for mailings. The game can be scaled to any screen, quickly updated for new films and seasons, and built-in analytics shows which mechanics hold attention best.
We applied the same approach to the chain's other entertainment offerings — and this led to a repeat order for new projects.
If you have a game that brings little value, or an idea you want to launch quickly — we understand what business needs and know how to deliver such solutions on a regular basis.
How to choose the porting format for your task?
Choosing a porting format is not a technical question but a strategic one. It directly depends on who your audience is, what budget is allocated for the launch, and what timeline you're ready to set aside for preparation.
We help weigh all three factors and choose an option that delivers maximum results at reasonable investment.
Start with the audience: where are your clients right now? If they play in the browser on any device — the HTML5 version will open the game without installation right away.
If your game is already known and the audience is used to a native app, it may be worth keeping the familiar format and focusing on optimization.
Budget and timeline determine the depth of porting. Sometimes a quick version is enough to test demand, and sometimes you need a full-fledged product with additional features. The more tasks the ported version solves, the higher the budget and the longer the timeline. We honestly show the difference and help you choose the stage that will pay off faster.
The main thing is not to fit the game into a format, but to choose a format for the task. For example, a minimal version is suitable for a short promo campaign, while an expanded version with analytics and new scenarios is better for long-term audience retention. We set the goals and select a solution for them — not the other way around.
As a result, you get not "porting for the sake of porting," but a growth tool: more reach, higher conversion to install or launch, and a clear work schedule. Contact us — in a short meeting, we'll review your task, audience, and budget to make an informed decision.
Frequently asked questions about game porting
Before porting a game to a new platform, the client always has questions: will the deadlines slip, will quality be preserved, will the source code suffer. We answer the most common ones.
How long does porting take?
Timelines depend on the complexity of the game and the number of platforms. Typically, basic porting takes 2–4 weeks; the exact schedule is fixed in the contract after requirements are clarified. At each stage, you see intermediate results, not just the final version.
What guarantees are there that the game will run stably?
We record key metrics in the technical specification and verify them on real devices and browsers. If something doesn't work as it should, we fix it at our expense within the warranty period.
How safe is it to hand over code and data?
We work under a contract with a confidentiality clause. The source code is stored in restricted access, and only project specialists can work with it. Upon completion, all rights transfer to you — we don't use your code in other projects.
What happens after the release?
After launch, we stay in touch: we help with integration, fix bugs, and update the game for new browser versions. We can sign a contract for long-term support — you get a specialist who has known the project from day one.
If you have any remaining questions — write to us, we'll reply within one business day.Ready to discuss game porting? Leave a request
